I'm In - 14th Time
Weird to think it's so many times!
As usual I will use Unity and my now-fairly-refined starter kit codebase.
For art I'll probably use Inkscape again, and for audio Reaper+VSTi into Audacity, or maybe even some foley.
There's a small chance I'll take a big risk and try 3D, and that would mean Blender.
Good luck everyone, and have fun!
